DELINTING DRYING TUMBLER.

Application filed April 23, 1320. Serial No. 376,036.

To all whom it may concern:

Be it known that I, CHARLES E. WVAREAM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Delinting Drying Tumblers, of which the following is a specification.

This invention relates to the art of laundry apparatus and'more especially to drying machines, as for instancethe tumbler type, the purpose of this invention being to remove the lint from the air after its passage through the drying chamber. In this way such lint is prevented from passing through the fan which is used for forcing the. air through the machine, and such lint will also not be allowedto pass to the outside atmosphere or to be further circulated through the machine.

The tumbler type of drying apparatus includes, in a general way, an air chamber, a heating chamber, and a drying chamber, all of these chambers having communication so that air from the outside atmosphere can be forced by means of a fan located in the air chamber through the heating chamber in which is enclosed som means for heating the air, thence through the cylinder of fo'raminous material in which the laundry is placed for drying and which receives a backward and forward rotating motion, from which point the air is forced back In such device this course just. re-cited or blown by means of the fan through an outlet to the atmosphere surrounding the machine casing. In either case it is desirable to remove the lint from.

the air after its passage through the drying chamber.

This invention might be embodied in different forms of structure but the preferred form will be fully understood from the following description and claims considered in connection with the-accompanying drawings.

Fig. 1 is an elevation of the tumbler type of dryer with a part bro-ken away; Fig. 2 is a transverse sectiorfal view taken on line a-a, Fig. 4; Fig. 3 shows an elevation of the pawl and ratchet mechanism for operating the delinting device; Fig. 4 is a front elevation with parts broken away;

Fig. 5 shows in perspective detail the lint conveyor; while Fig. 6 shows in perspective the lint screen. J

By means of a fan indicated at 1 in Fig. 2, fresh air from the outside atmosphere is forced through the warming chamber, not shown in the present drawings, thence through the drying chamber 2 within which is enclosed the tumbler with its foraminous wall 3, from which point the air is f rced into air space 6 and back to the fan again to be forced through the same circuit or to be partly forced to the outside atmosphere,

as the case may be. A door 4 hinged to the tor 31 which drives pinion 30 and in turn the meshing gear 28 which carries pinion 29, gear 27 meshing with pinion 29 and the main gear 26 on one of the trunnions of the tumbler, backward and forward motion is transmitted to the drying cylinder 3 and likewise to the ratchet 23 mounted upon the shaft of gear 26, this ratchet 23 having cooperation with pawl 24 mounted upon the gear 22 which is loosely mounted upon the trunnion of gear 26. Then by ineansof a chain or belt connection 32 between sprockets 22 and 33, operation of the delinting conveyor 16 upon shaft 34 is effected; that is, when shaft 25 with its ratchet 23 is operating in clockwise direction, pawl 24: during the reverse direction riding freely upon ratchet 23. The mechanism for giving the intermittent backward and forward motion to the tumbler 3 is not shown herein as this means is well known in the art.

'Upon opening or closing door 5 which carries near its lower edge, as shown at 21 a finger 21 with a curved or cam shaped portion near its inward end, rod 17 is given a downward motion by engagement'of the cam 21 upon roller 19 against action of the spring 20 mounted on said rod between the guide 18 and the clevis 19 in which 15 shown in Fig. 1, finger 21, rod 17 and lever '15 are outside the casin while lever arms 40 are inside. Thus the screen member as a result of such operation is caused to move backwardly toward the stop 11 mounted upon the lower part of the partition surrounding the drying chamberJ Then, when cam member 21 has passedentirely over idler 19, this screen member 10is allowed to fall by gravity against the stop 12 which is provided on the extension 9 ing device.

of the partition member surrounding the drying chamber. The extension of this partition member cooperates with the like member 8 to form a passageway for the air from the drying chamber to the delint- The wall member 8 just referred to is acontinuation of the partition member whichsurrounds the front part of the drying chamber and has a decided curvature as shown in Fig. 2, whereby the air carrying the lint from the drying chamber.

is deflected onto the lower face of the screen member to which the lint will adhere because of the moisture carried by the same.

The screen member 10 which is hinged at 13 to angle, iron-37, consists of a. mesh 38 provided with reinforcing U shaped strips 41 and also wiper felts 39 secured in any suitable manner to the strips 41. The felt strip. at the bottom is also secured to the angle bar as shown in Fig. 6. These felt strips keep the lint out of the main part of the machine casing. Strips 35 extend across the mesh as a bearing surface for rollers 14.

The other part of the deli'nting device as shown in Fig. 5 is termed a lint conveyor which consists of four blades 35* arranged at 90 upon shaft 34. These blades may be of any suitable rigid material and are provided at their edges Withwiping strips 36 and are also arranged in overlapping relation about the axis 34 as shown at 42 in Fig. 5. This part of the device is so arranged that the wiper felts 36* neatly wipe over the lower end portion of plate 8 and also over the floor of the casing. An inclined false bottom section 44 is also-provided the incline of this bottom section or plate 44'being determined by the path described by the edges of the wiper felts 36. In this way, the deposited lint ismmoved from the lower portion of the chamber in front of and below the lint Leeaeoa collector and is transferred or conveyed to the pocket formed in the front corner of the machine casing and is prevented from being spread through this part of the inachine casing. The upper end of the inclined false bottom member 44 is secured to the angle iron 37 as. shown in Fig. 2.

From the above it will be seen that the lint carried by the air from the drying chamber ,will be forced through the p-as-' sage-way between the wall members 8 and 9 and deflected by the curved member 8 over against the screen member '10, the air being allowed to pass on through the screen. This lint carrying more or less moisture which it has accumulated upon its passing through the drying chamber will accumulate upon the screen member 10 during-its periods of rest. Operation of the rollers 14 will cause a rearward swinging and subsequent suddenreturn of :the screen member to its seat 12, accompanied by a decided jarring motion which will free the lint from the screen member 10 and allow it to fall upon the blades 35. Then, upon operation of shaft 34 at intervals, the lint received upon the horizontal blades 35 will be thrown forwardly and formed into the pile 43 in the front part of the main casing, door 44' allowing removal of such lint as desired.

An air intake is indicated at 45 and the. drive shaft for the fan at 46.
